132 XEROPHILA ITALA. 
Var. hyalozonata Cockerell. 
Helix ericetorum var. hyalozonata Cockerell, Naturalists’ World, Dec. 1885, p. 223. 
SHELL pure white with translucent bands or markings. 
This is a local and interesting albine form of the species, but it oceurs more or 
less sporadically throughout the range of the species, and occasionally occurs within 
a limited area, associated with virgata and other species sharing the same pecu- 
liarity, implying that the local influences have probably contributed to its evolution 
and perpetuation. 
The var. dentiginosa when in the albine transparently marked form may be 
known as hyalozonata-lentiginosa. This variety is the common form about Clara, 
King’s Co., Ireland.

Helix ericetorum var. minor Germain, Moll. Maine et Loire, 1903, p. 121. 
The var. cornea is small and horn-coloured, with four transparent zonules. 
The sub-var. subpellucida is described as possessing translucent brown banding, 
through which the body of the animal appears black, and links with var. hyalozonata. 
It is also the var. subhyalozonata of Wright. 
The sub-var. minor of Germain is by its other characters referable to the present 
form. It is described as thin, yellowish-horn tint, with clear fawn-coloured semi- 
transparent bands, and forms a connecting link with var. dwtescens and var. sub- 
nellucida Jenner.
